    Suspect the Power Supply. Weak Voltage power rail, and specifically the 12 Volt power rail. 11 to 13 Volts = OK, less than 11 Volts it's time to replace the Power Supply. 1) ALL the LED lights use less than 1 Watt of power. 2) EACH fan uses 2 to 3 Watts. 3) A typical Processor can use 51 to 125 Watts. Depends on what Processor it is. (Older Processors such as Intel Pentium III's use less than 51 Watts) Not enough power for the Processor means the Processor won't turn on. No Processor operating, No computer. This is why you may see LED lights light, and perhaps fans spin, but if the Processor doesn't have enough power to turn on, NO computer.

SOURCE: Acer Veriton 6800 PC Desktop will only beep will not boot.

Hi Just checking first of all you have tried another memory module. This sounds like a faulty RAM. Please try and get back to me if that doesn't fix it. Thanks, Lolita

Blow the dust off the heat sinks and remove one memory card then give it a try .. replace and romove the other one.. It is likely a faulty memory card.

SOURCE: Acer power up problem and no picture on screen

removethe video car and dimm memory and any other plugged in cards
leave the monitor unattached.
start the machine
if it beeps exactly as u said, the motherboard is faulty and must be replaced.
If it doesnt, or gives out a different beep pattern, turn it off, add the memory dimms ack, switch on again.
If it beeps continuously your memory is bad and you may just be able to go buy some replacements. If you have never removed/installed dimms be careful they only fit in one way around.
If the beep is absent/different to the original problem beep, turn off the macchine again and add the video card - do not attach the monitor. reboot and listen again If u have recreated the original beep that it failed on, its the video card.

This is the standard diagnostic process and can be repeated with the addition of each accessory, monitor, keyboard etc. until you find the culprit. Failed hard disks/CD's/DVD/Floppy will not give you this beep error usually. It is most likely faulty memory chips. If youo have really good manuals that came with the machine, you can look up the beep code to identify the problem as they are like morse code...the beep pattern tells u the fault.
Hope u can resolve it yourself and save some cash!

SOURCE: I have an Acer Aspire AM1641 U1521A desktop that

Power Supply. Weak voltage power rail.

Has enough power to light LED lights, maybe spin fans, (Or spin a few times, and stop), but not enough power to turn the Processor on.

1) ALL of the LED lights combined use less than 1 Watt of power.

2) EACH fan uses 2 to 3 Watts of power.

3) A typical Processor can use 51 to 125 Watts of power.
Depends on what Processor it is.

Acer Aspire M1641-U1521A?
Intel Pentium Dual Core E2180 (2.0GHz)

http://en.wikipedia.org/wiki/List_of_Intel_Pentium_Dual-Core_microprocessors#.22Allendale.22.2C_.22Conroe.22_.2865_nm.29

Can use up to 65 Watts. (TDP)

The Power Supply used is a 250 Watt unit. Acer isn't known to use high quality power supply's. It's a generic low quality Power Supply.

[ However in all fairness to Acer, if the inside of the computer, AND the inside of the Power Supply, isn't cleaned out on a regular basis as needed, this can cause Power Supply failure also.

Use a can of compressed air for computers, with the plastic 'straw' attached. Hold onto the can with one hand, use the other hand to hold onto the straw, shoot air through the ventilation holes of the Power Supply's case. (Computer unplugged from power)

Come around to the back of the computer, use the air to clean the Power Supply's fan blades, center hub, and surrounding cage. (Shroud)

When the cooling components for the Power Supply, (Fan and Heatsinks used inside), become clogged with dust, dirt, etc., the cooling capacity drops tremendously.

The Power Supply overheats.
Heat = Wasted Energy

The Power Supply strains to keep up with the call for power, but eventually cannot, and fails.
Components inside the Power Supply fail ]

Replace the Power Supply.

Got an acer aspire ax3812 tower is on but screen stays blank got any ideas


Change the internal Ram sticks. This can cause a "Hold" in the BIOS boot process, thereby stopping the machine from going to the Operating System. Hope this helps.

Acer aspire sa80-9b7z won't start up. Fan starts


Firstly check the monitor, if you get 8 beeps as it is starting up, this points to graphics problems. Trying another monitor. If the problem remains, swap the graphics card or use the onboard graphics card.
If this fails and, more importantly, you are not getting any beeps (single beep would indicate your CPU is ok), the problem is likely to lie with the motherboard.
To help you further, please repost with the number of beeps if any, you get as it tries to boot up

My Acer Aspire M1201 Desktop will not boot. I turn the power on but all I get is the Acer logo followed by "No Signal" and the monitor goes blank. I keep hoping I will finally hear the beep noise...


Hi,

If you are seeing the Acer logo on boot up then the machine is working. The problem will be your graphics drivers being corrupt.
Try starting the machine in Safe Mode. To do this repeatedly tap the F8 key as it's just starting up. It should take you to an advanced menu with Safe Mode at the top, select that with the cursor keys.

If it allows you to boot in safe mode then wait until Windows loads and then right click on My Computer/Computer, select manage from the sub menu and then Device Manager.

Click on Display Adapters and uninstall the drivers. When its done unistalling the drivers restart the machine in normal mode. It should boot into Windows. If it lets you boot into Windows I suggest that you download and install the latest drivers from Acer's support website.

If you need anymore help please post back.

Good luck and regards.

Acer aspire one power button comes on but screen doesn't come on.


1/ Take a close look at the display in bright light; can you see anything there? (If so then the CCFL (or its power supply) needs replacing on the display
2/ hook up an external monitor and see if that works (or at least if the light stays green on the monitor)
3/ Any boot beep? any "Windows sound"?
4/ try removing the battery and (using only external power) see if it starts.
4/ remove the battery AND the external supply, hold the power switch in at least 30 seconds. Hoojk it up again, try it.

Hi, I have an Acer Aspire 5920G. My problem is when the laptop is switched on it sounds like it's booting but the screen stays blank? Have you any idea what can cause this? Regards, Dan Pook...


Hello
I think your graphics card or screen is broken on your Acer Aspire 5920G, one thing you can test is to connect at external monitor to your laptop. If you dont get any picture then its your graphic card broken, if you get picture it is your screen. also try to adjust the screen light.

Acer aspire e360-2b73


Mine did that too, I have sent it to Acer for Warranty Acerization, it came back in a week booting fine. Worked for 3 months and then quit again. These boards are used y other cheapos like Gateway and Packard Bell. Solution - trow away the motherboard, keep the CPU and RAM.

My pc won't work!


Assuming you get 2 beeps on boot up, take the side off your pc and see if the whirring sound is coming from your hardrive, if so you may have a damaged sector on your hardrive where the boot sector is. If you have a Windows XP disc come back here, if not you need to take your hardrive to a friends pc and set your hardrive as the slave drive before connecting up. When booted up go to My computer and right click on your hard drive (could be 'D' drive or 'E' or 'F')depending on other pc. Go down to properties then tools tab and click error checking and let the system check for errors and automatically repair them. Your rating is importanat
